Bug: LLM provider/model forms do nothing on submit (saveLLMProvider/saveLLMModel not in global scope)

[sealkrach]

Description

In the Admin UI, clicking Save on the Add/Edit LLM Provider or Add/Edit LLM Model modals does nothing. The page silently reloads without saving.

Root Cause

In mcpgateway/templates/admin.html, both forms use bare function names in their onsubmit handlers:

<!-- Line ~2081 -->
<form id="llm-provider-form" onsubmit="saveLLMProvider(event)">

<!-- Line ~2179 -->
<form id="llm-model-form" onsubmit="saveLLMModel(event)">

However, saveLLMProvider and saveLLMModel are not exposed as global functions. They are only registered on the window.Admin namespace in admin.js:

Admin.saveLLMProvider = saveLLMProvider;
Admin.saveLLMModel = saveLLMModel;

When the form is submitted, the browser cannot resolve saveLLMProvider as a global, event.preventDefault() is never called, and the form falls back to a native HTML submission (page reload). No provider or model is ever saved.

Fix

Change both onsubmit attributes to use the Admin. prefix:

<form id="llm-provider-form" onsubmit="Admin.saveLLMProvider(event)">
<form id="llm-model-form" onsubmit="Admin.saveLLMModel(event)">

Steps to Reproduce

1. Open the Admin UI → LLM Settings
2. Click "Add Provider" and fill in the form
3. Click "Save" — nothing happens, page reloads

Impact

The entire LLM provider and model management UI is non-functional. Users cannot add or edit providers/models through the admin interface.

Environment

Affects all deployments (Docker, PyPI). Bug is in the template source.
